WARPING-MACHINE.

Specification of Letters Patent.

Patented Jan. 26, 1909.

`Application filed July 28, 1908. Serial No. 445,728.

reference marked thereon,which form a partl of this specification.

. 1n the operation of warping machines it is well known that the contlnuous wiping contact of the threads of the warp againstthe dents `of the J cross reed, and particularly those dents more or less near the ends of the cross reed, soon wears nicks or depressions therein which are objectionable not only that they sooner or later render the reed unadapted for further use but act Vto catch knots or irregularities in the threads, with the result that the threadsbreak under the ull exerted thereon by the reel of the machine; the warp turned out is thus poor in (quality, to say nothing ofthe annoyance an loss of time which the warper has to cope with. Thus, whenever lthe threads run slightly uneven or large in size, or if the silk is slubby, the threads in running through the nicks are stripped, or several fibers are broken, and these stripped or half broken threads run into the warps, causing great loss of time in iecing up in passing through the harness and) reed in the weaving process, as well as loss of production and imperfect merchandise. Again, when the warper is taking the leash cross, in moving the threads up and down in the cross reed past the nicks, the pressure of the threads against the nicks breaks many fibers in the threads and these half broken threads run through onto the warp, causing great loss of time andproduction in the weaving in forming s lit ends behind the weavers reed, and'ma ing imperfect merchandise.

The object of this invention is to provide, in connection with the reed of a Warping machine, means whereby the difficulty above referred to may be entirely overcome and this 1 accomplish, in such a way as not to interfere with the o erator watching the threads as they `pass tllroulgjl1 the reed, by providing a rising and fa g bar which keeps the threads constantly moving up and down, i. e., inthe direction of the length of each dent of the reed, so that they do not constantly wear in one lace on the dents in order, further, that sai bar may, at the will of the operator,clear the war so that the operator may form the sheds therein as occasion 'may require, l provide means for so mounting the said bar that it may be temporarily swung out of contact with theV threads.

My invention will be found fully illustrated in the accompanying drawings, wherein- Figure 1 is a side view of a warping machine provided with my improvement, Fig. 2 is an enlarged plan view of my improvement and so much ofthe warping' machine as is directly related to it; Fig. 3 isa front view of what is shown in Fig. 2, and, Fig. 4 is an enlarged detail view in side elevation.

In the drawings, a, is the frame of the machine, l) the reel; c the reed carriage, d guiderods on which the carriage moves laterally of theframe a, e a rotating screw with which thecarriage is disconnectively connected so that, at the will of the warper it may partake of the desired traverse movement or be moved by hand from point to point along the guide-rods in setting it for the laying-on of each section of warp on the reel, and f the usual sprocketandchain drive for rotating the screw from the reel shaft g.

On the end of the usual arm h forming a part of the carriage c is arranged the cross reed i; to the ends of the base or lower rail j ofthe frame of the reed l attach, by means of screws lc or otherwise, the vertical brackets Z. The rail j being somewhat thicker than the reed proper and projecting forward of the front face of the reed, the uprights l are so arranged that they stand slightly forward of the plane ofvsaid front face of the reed, as best seen in Fig. 4. 1n said brackets is journaled a horizontal shaft m on which, close to the outer sides of the brackets, are fixed cams n, the same` serving to revent incidentally endwise movement of t e shaft in its bearings. On said shaft m is fulcrumed a frame 0 comprising the uprights the lower endportions of which said sha t penetrates, and the fiat connecting bar g, the upper end-portions of said uprights being provided with the slots r extending longitudinally thereof the slots r receive the ends of a glass-bar s.

Cams nare set on the shaft (m) so that their highest parts are in the same radius from the shaft and against them bear the lower ends of the glassebar carrying forks t arranged to move in guides u secured to the outer face of each bracketl one above the other b y means of screws c; the front arm w of the bifurcated portion of each fork is made somewhat shorter than the rear arm so as to allow the glass-bar to be raised in the u rights p sufe ficiently to clear the fork, whereupon the frame o with the glass-bar may be de )ressed to the position indicated by broken lines in Fig.` 4, in which position the frame rests against the bottom rail of the reed-frame,

lthe glass-bar being then temporarily out of contact with the warp.

It willbe understood that when the parts are in the position indicated in Fig. 4 in full lines the rotation of the cams will cause an intermittent rise and fall of the glass bar which will raise and lower the warp so that the threads thereofwill be prevented from continually wearing on the same points of the reed dents and so forming nicks in them. The shaft carrying the cams is rotated as follows: Said shaft carries at one end a pulley :r over which is extended an endless belt y which passes around a roller 2 having its trunnions I ournaled in the brackets 2 secured to the frame a, the roller being arranged parallel with the path of traverse of the carriage c; on the right-hand trunnion of the roller is fixed another pulley 3 over which and another pulley 4 on the shaft g of the reel extends an endless belt 5. Thus as the reel rotates it causes the rotation of the shaft m carrying the cams n, the roller .e allowing meanwhile the unimpeded traverse of the carriage. y

I do not wish to be limited to the details of construction herein set forth, but,

I-Iaving thus fully described my invention,

, what I claim as new and desire to secure by Letters Patent is:

l. The combination., with the reed, of means for moving the threads in the reed transversely of their length comprising a thread-engaging member extending transversely of the reed-dents, cams, a rotary shaft carrying said cams and also extending transversely of the reed-dents, brackets carried by the reed and forming bearings for said shaft, and devices, bearing against the cams and engaged by said member, for transmitting a reciprocatory motion from the cams to said member, said devices being guided in said brackets, substantially as described.

2. The combination, with the reed, of a thread-engaging member extendingr transversely of the reed-d ents, means for effecting a vibratory movement of said member in the direction of the length of the reeddents, said member being movable out of position to engage the threads, and means, movable with said member out of position to engage the threads, for supporting the same when out of said position, substantially as described.

3. The combination, with the reed, of a thread-engaging member extending trans versely of the reed-dents, means for effecting a vibratory movement of said member in the direction of the length of the reed -dents, and means for guiding said member in its vibratory movement, said last-named means being movable toward and from the thread plane and said member being movable with said means, substantially as described.

4. The combination, with the reed, of a thread-engaging member extending transversely of the reed-dents, means for effecting a vibratory movement of said member in the direction of the length of the reed-dents, and a frame fulcrumed on an axis also extending transversely of the reed-dents and having slots extending radially with reference to its fulcrum and receiving said member, substantially as described.

5. The combination, with the reed, of a thread-engaging member extending transversely of the reed-dents, means for effecting a vibratory movement of said member in the direction of the length of the reed-dents com prising vertically reciprocating forks having their forked portions uppermost and receiving said member, means for guiding said forks, and a frame fulcrumed on an axis also extending transversely of the reed-dents and having slots extending radially with reference to its fulcrum and receiving said member, substantially as described.

6. The combination, with the reed, of a thread-engaging member extending transversely of the reed-dents, brackets carried bythe reed, a shaft journal'ed in said brackets, cams arranged on said shaft, forks guided in said brackets and having their forked pertions uppermost, said forks being engaged with the cams, and a frame fulcrumed on said shaft and having slots extending radially with reference to the shaft and receiving said member, substantially as described.

In testimony whereof, I have hereunto set my hand this 23rd. day of July, i908.
